Description
Technical field
The present invention relates to plastic tube preparation field, more precisely, being a kind of modified plastics for being used to manufacture drainpipe.
Background technology
With Ministry of Construction's promotion and application chemical building material, continuing to increase for the dynamics of backward building material product is eliminated in limitation, with
The fast development and urban infrastructure etc. for China's residence industry are pulled out into increasing, chemical building material as one kind after steel, timber,
After cement, the another important construction material grown up is shown strong on the stage of China's modern architecture industry
Big vitality and vast potential for future development, plastic pipe as chemical building material important component, with its superior property
Can, health, environmental protection, low consumption etc. are accepted extensively by users, and are largely used in architectural engineering.
UPVC drainpipes account for 50% or so in China's plastic tube industry yield, are that China is most widely used, using compared with
It is early, user's plastic pipe the most known, but in the detection it was found that exactly UPVC drainpipes have many ask
Topic.1st, shock resistance is poor.By GB/T5836.1-92 standard detection falling weight impact tests, detection for many years is found, First Pass Yield
Only less than 50%, many products even 10 Secondary Shocks, all rupture.2nd, tensile strength and toughness are poor.Good UPVC manages it
Tensile strength curve should have substantially surrender, and elongation percentage is larger.And the tubing of difference often appears as fragility, elongation percentage is low and easily broken
Split.3rd, softening temperature is relatively low, it is easy to which heat is deformed.Show on experimental performance, be that vicat softening temperature is relatively low（It is less than
79）, some producers are raising softening temperature, and amount of filler is simply increased in dispensing, and softening temperature can be improved really by so doing
Degree, but make tubing other performance, especially impact resistance, tensile strength, toughness are substantially reduced, therefore to improve softening temperature
Degree, just should be above and below auxiliary agent selection, raw material proportioning, production technology and manufacturing machine without reducing or seldom reducing other performance
Time, can not rashness treat.
